[Tkinter-discuss] Tkinter with Eee Top touchscreen PC

[F. Curatelli]

Hi all,

I've just tried Tkinter on an Asus EeeTop PC with touch screen for an 
application
which needs to manage: 1) directly clicking on specific screen areas, and
2)  selection after a dwell time. However in both cases there are some 
problems.

For the first option I've used the recognition of  the <Button-1> and 
<ButtonRelease-1>
events; indeed the two events are managed but this occurs only when the 
finger/stylus
is released (in other words, the press event is not produced until the 
realease event
is produced too). Why does this happen?  After all the press acton is 
recognized by
the system, because on the screen a visual feedback (a set of circle 
shape waves
around the touch point) is instead displayed. the
The fact that the recognition of  the touch is not immediate and has to 
wait until
the realease action does not allow to know  when to start the dwell time 
for the
second option. Any idea?  Thanks in advance
